To all whom it may concern.'

.Be kit known that I, CHARLES H. CLARK, a citizen of the United States.l and a resident of Library, in the county of Allegheny and State o'Pennsylvania, have invented a new' and useful Improvement in Dumping Cars, of which the following is a specilication.v

My invention relates to railroad rolling stock and consists in an improvement in dumping cars. In one of the familiar `types of dumpmg cars, a gondola body is so mount'- ed upon the car underframe that itmay be tilted thereon with the floor sloping to either side of the track desired.. The car sides are formedl of doors hinged along the edge of the car Hoor and when the body is tilted, the doors on the side nearest the ground open until they form an extension of the car floor and over which the' load is discharged to that side of the track. The body is ordinarily self-righting after the load 1s dumped. v

The object of my invention is to provide such a d mp car with a vertical extension of the sides and ends for the purpose of increasing the capacity of the car and to providemeans for preventing the extension from interfering with the dumping of the load and with self-righting of the tilted body.

Inthe'accompanying drawings, Figure 1 is an end elevation of a car of the tvne I have described, with my improvement applied,

Fig. 2 is an elevation of one corner of the car looking towards the dumping side, and Fig. 3 is a transverse, verticall section thru the car when it is in dumplng position.

i Mounted on the usual trucks is a car underframe having centers sills 1, ends sills 2 and corner posts 3. The latter consist of channels facing outwardly at the sides of the car end and mounted on the end sills 2. Doors 4 comprise the sides of the car and each door is' hinged and adapted .to turn on its hinges to form an extension o f the car floor for dumping urposes as shown on the right hand side of Fig. 3'.

Those familiar with the art are acquainted `With various means for tilting the car body and opening the doors but such equipment forms no part of my present invention and I do not illustratey same.

.rack raising' strut 13.

'rile @as of the en any are am and support an extension for the-ends and sides,

which term a rack and which gives the car additional capacity. The rack is a rigid, rectangular frame wthout'top or bottom. Channels 5 form its sides and a stiener member 6 extends longitudinally of each channel 5 wit`h its web at right angles thereto and with its inner flange riveted to the web ci channel 5. At' intervals, struts or brackets 7 unite the outer flange of channels 6 and the upper flange of side 5. The ends of the raclr consist of inverted U shaped steel structures having one leg 21 lian ed to rest upon the car end and the other eg Af2.2 extending downwardly to overlap the end of the car body. The sides and ends of Athe rack are rigidly connected and braced. 'The reinforced construction constitutes the naled in a bearing angle 16 mounted on an angle end plate 11 of the car body. Each end of the car isequipped with one bearing clip 12 which may be bolted to either one of angles' 10v and cooperate with that angle to form a hinge for the rack.

Fach 'end of the car is provided with a The ends of this strut are slotted at 14: and 15. A horizontal pin 16 is mounted on each body corner post 3 and is adapted to be inserted thru slot 14 of strut 13. Spaced trunnionvbrackets 18 are provided on each end of the rack and a pin 17 is adapted to be mounted in one bracket 18 and to be inserted thru slot 15 in strut 13. Nuts 19 and 20, re-

spectively, with suitable washers. hold strut 13 in position on pins 16 and 17.

Strut 13 is of such length that'the maximum distance between the opposite ends of slots 14 and 15 will accommodate the pins when the body and underframe have the relative positions shown in Fig. 1.

When the car is dumped, the car body is tilted to the right and pin 17 moves to the position shown in Fig. 3 which is nearer to pin 16 than its original position. During the first part of the tilting movement, strut'13 slides down pin 16 until the upper end of slot 14 engages the pin and pin 17 then slides down slot 15 until it reaches Klatter part of the movement.

the lower end of the slot. vents the entire rack 'from the body bodily during ment of the latter the Strut 13 preaccompanying further tilting moveby swinging the side oi rack on the dumping side of the car from the body on hinge portions 9, and 12 to prevent vmaterial from overiiovving the and the rack substantially end.

If it is desired to dump the car in the opposite direction, nuts 19 and 20' are removed and strut 13 is shifted to pins 23 and 24 on the other side of the car and bearing clip l2 is unbolted from one bearing angle and shifted to the opposite one thus reversing the hinge position of the rack.

ln a car of the tilting type illustrated, the return of the body to upright position is secured by the preponderance of weight on the non-dumping side dumped. The use of strut 13 provides means `for increasing that preponderance during initial righting movement by sup-v porting a very substantial part of the weight of the rack from the car underframe andy by having that portion which is borne by the body supported on the sideV where the preponderance of weight must lie to right the body. So it will be noticed in Fig, ii that all of the rack weight borne by the tilted body is supported at the rack hin which is on the left or return side of t body support. vWhile the dumpingside resumes its share of the weight of the rack before the body is upright, the preponderance of the Weight of the body and rack at the point of resumption is then on the left hand side of the body support due to the fact that the center of mass of the body and rack moves to the-left more rapidly than the supporting oint for the body. rocker on the truck roc er stand. lf strut 13 beomitted supported in part at the dumping side of the body ends at all times, the location of the center-of mass would move so far to the right of the supporting point, in dumping, as to impair the self-righting feature of the car.

'l have shown two trunnion brackets 18, spaced from the center of the car body and, in the car illustrated, I prefer such construction, but the assembly could be modiiod to use only one such bracket and in that case, strut 13 need not be made removable from' the rack. The matter of the rack sides and ends is also optional as is thel supportand pivotally after the load isk insegna ing point for the lower end of strut 13. in all the details of my invention, modifications are easilymade withoutdeparting from its principles.
